What's the best time to run a washing machine? For an estimated monthly cost, divide the estimated yearly cost by 12. Simply multiply this number by the average electricity rate in your area to get an estimate of how much you spend to power your washing machine each year. Remember that yellow Energy Saver sticker we mentioned above? If you want to know how much electricity your washing machine uses (or at least is supposed to use), take the estimated yearly electricity use in kWh – this is probably your best bet for an accurate number. Calculate how much energy your own washing machine uses. Make sure to keep in mind your current and future electricity usage, and talk about how that could change with your installer for the most accurate quotes. Looking to offset your electric bills (and the energy these appliances use) with solar? When you sign up (for free!) on the EnergySage Marketplace, you can compare solar quotes from high-quality, local solar installers. Note: average electricity rates are based on October 2021 data from the U.S. Voltage is the water pressure, amps are the amount of water flowing past any point, and wattage is the overall rate of water flow through the pipe. You can think of all of these terms like water flowing through a pipe. Simply put, kilowatt-hours are electricity consumption over time. Kilowatt-hours (kWh): lastly, kilowatt-hours are how your electric bill measures your energy usage. Put simply watts are the rate of electricity consumption. Watts (W) and kilowatts (kW): multiplying volts x amps get you watts (or wattage). Put simply amps are the amount of electrons (which make up electricity) flowing through a circuit. Put simply voltage is the speed of electricity passing through a circuit.Īmps (A): amps (short for amperes) are a measure of electrical current. Volts (V): volts (short for voltage) are measures of electrical pressure differences. We've already mentioned most of them – here are a few definitions to keep things straight: There are a lot of terms you can use to describe how electricity flows and is used by appliances. Assuming you run your washing machine an average amount (3 days per week, or 156 days per year), here's how much electricity you'll use over the course of a year: How many watts do different washing machines use in a year? If you run a 900 W washing machine every day, that's 6.3 kWh of electricity per week, 27.3 kWh per month, and 327.6 kWh per year.ĭifferent-wattage washing machines use different amounts of electricity over the course of a year. Running that same washer three times a week comes to 2.7 kWh per week, 11.7 kWh per month, and 140.4 kWh per year. If you run a 900 W washing machine once a week, that's 0.9 kilowatt-hours (kWh) of electricity per week, 3.9 kWh per month, and 46.8 kWh per year. To cover a range of schedules, we'll outline three scenarios: using your washing machine once a week, three times a week, and every day of the week. How much you run your washing machine has the biggest impact on how much electricity it uses over time, and households have all sorts of laundry routines. Most washing machines use between 5 and 15 amps and connect to a 120-volt outlet. On average, a washing machine uses 400 to 1,400 watts (W) of electricity, depending on the model.
